Thank you, Helen. So today, I'll focus on our lead asset, EVX-01, our personalized neoantigen cancer vaccine currently in Phase 2 in advanced melanoma. Then I'll present our new off-the-shelf EVX-05 vaccine program, demonstrating the scalability of our AI-Immunology platform into the hard-to-treat and deadly brain cancer, glioblastoma. Lastly, I'll showcase how AI-Immunology identified T cell epitopes are relevant in controlling CMV infections. So as Helen mentioned, we will present 3-year EVX-01 Phase 2 outcome data at the ESMO Congress in October. And this data includes evaluation of the vaccine's effect as stand-alone and also in combination with anti-PD-1 treatment. The data will potentially give further insight into enhanced treatment effects and also the durability of EVX-01 induced immune responses. And collectively, these data provide a more comprehensive assessment of the full potential of EVX-01, strengthening the already strong clinical data package. So looking back at previously announced data from the EVX-01 Phase 2 trial, we reported strong EVX-01-induced immune activation at the AACR Meeting in April. So we were able to show that 86% of the EVX-01 vaccine targets triggered a tumor-specific immune response, which is a substantially higher frequency than what has been reported for other similar vaccine candidates. Furthermore, we also showed that 86% of the immunogenic vaccine targets induced a de novo T cell response, meaning that EVX-01 specifically triggers novel T cell responses rather than amplifying existing responses. And this is very important as induction of de novo T cell responses has been linked to clinical benefit. And at the ESMO Congress last year, we reported 2-year outcome data, including a 75% overall response rate, 25% complete responses, and 92% of the patients still being in response, indicating durable clinical benefit. And importantly, more than half of the patients converted into an improved clinical response upon EVX-01 treatment. So over the last approximately 10 years, personalized neoantigen vaccines have shown promise across several early-phase clinical studies. And with the Moderna and Merck announcement yesterday, we can definitely say that the field is moving from promising experimental immunotherapy towards a clinically validated therapeutic modality with a clear and realistic path to regulatory approval. And these data are not just only a win for Moderna and Merck, but it's a win for the entire field as they broadly validate the personalized neoantigen vaccine concept. So overall, with our encouraging EVX-01 data and with the validation from Moderna and Merck, we believe that we are well-positioned as we move forward towards further value creation. And so let's turn our focus to our off-the-shelf cancer vaccine programs. So in collaboration with Duke University, we are developing an off-the-shelf vaccine, EVX-05 for glioblastoma or GBM, targeting conserved antigens as announced earlier this week. So GBM is the most common and most aggressive primary malignant brain tumor. And despite surgery followed by chemoradiation, outcomes remain very poor with a median overall survival of approximately 1 year, underscoring a significant unmet medical need. So our EVX-05 approach builds on the same novel and broadly applicable concept as EVX-04 as it is designed with AI-Immunology to target conserved tumor-specific antigens derived from endogenous retrovirus elements or ERVs, which are part of the dark genome. The target selection process allows for broad tumor coverage despite immune and tumor antigen differences across patients. So we have applied AI-Immunology, so our AI-powered target discovery approach, and identified an optimal set of ERV fragments based on cross-patient relevance and immunogenic potential. And we have mined patient sequencing data identifying approximately 1.5 million ERV fragments and selected 16 of these as the fragments that will be included in the EVX-05 vaccine. So next steps include lead candidate selection and IND-enabling activities prior to a first-in-human study that is expected to be conducted in collaboration with the world-leading GBM experts we are collaborating with at Duke University. So our other off-the-shelf cancer vaccine program, EVX-04, is also progressing well. So EVX-01 targets multiple conserved ERVs, in the case of this program identified in AML patient samples. So as Helen mentioned, we presented novel data at the European Hematology Association Congress in June, demonstrating that the EVX-04 vaccine is expressed and secreted by human cells, enabling immune recognition and activation. So further, we showed that the 16 ERV targets included in the EVX-04 vaccine activates human immune cells across different HLA types and that these ERV-reactive immune cells can mediate targeted cell killing, indicating not only immune recognition, but also relevant functional impact of these vaccine-induced immune cells. So collectively, these data highlights EVX-04's potential as a new effective therapeutic cancer vaccine. And we look forward to reporting further data as the program progresses towards regulatory filing later this year. So another promising program presented at a scientific conference during the summer is our EVX-V1 cytomegalovirus or CMV vaccine program. So in EVX-V1, we are using AI-Immunology to design known targets, so optimizing them, and also to identify previously unexplored vaccine targets. And at the International Herpesvirus Workshop in July, we presented new data demonstrating that T cell epitopes discovered with AI-Immunology have the potential to control acute infection, latency, and also reactivation in CMV-infected mice. And this is a key finding as it complements previous results, demonstrating the ability of both novel and optimized known B-cell antigens to reduce viral infection. And the data will guide antigen selection for a broadly protective CMV vaccine candidate and as such, represent a very important step forward for the EVX-V1 program. So having highlighted progress across our key R&D programs, let's now focus on our AI-Immunology platform and the data validating its ability to generate high-quality product candidates. So AI-Immunology is clinically validated with positive outcome in 3 out of 3 oncology trials. Preclinically, we demonstrated vaccine proof of concept across multiple disease areas, including cancer with our ERV-targeting vaccines as well as in infectious diseases with several candidates against bacterial and viral pathogens. And importantly, the EVX-01 concept is highly scalable with potential in other solid tumors. And additionally, the novel ERV-based cancer vaccine concept is used in both our off-the-shelf programs, EVX-04 and EVX-05. So finally, AI-Immunology supports multiple modalities, including peptides, recombinant proteins, DNA, and RNA platforms, enabling both pipeline and partnering potential. So in conclusion, we have demonstrated strong progress across our R&D pipeline, and we look forward to providing updates as our programs progress. So with that, I'll hand over to Thomas, who will present our quarterly financial results.
